La Bestia
La Bestia ("The Beast"), also known as El Tren de la Muerte ("The Train of Death") and El Tren de los Desconocidos ("The Train of the Unknowns"), is a network of freight trains that start their route in southern Mexico, near Guatemalan border, and travel north to the outskirts of Mexico City, where they connect with other freight trains heading to different points along the Mexico–U.S. border. It is estimated that each year, between 400,000 and 500,000 migrants, the majority of whom are from El Salvador, Guatemala, and Honduras, ride atop these trains in an effort to reach the United States.
